Letters Patent No. 96,329, dated November 2, 1869; antedated October 27, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: v

Be it known that I, THOMAS LING,of Hartford, in

the county of Hart-ford, and the State of Connecticut,

have invented a new and useful Improvement in Self- Adjusting or Anchoring-Pumps; and I declare the following to be a full andI exact description thereof,

reference being had to the accompanying drawings and to the letters of reference marked thereon, forming a part of this specification.

The main features of the pump upon which I have made an improvement are those ofthe pump patented by me, March 27, 1855; and

The improvement aimed at herein has two partsthe 011e an improved valve for said pump, and the other the substitution of an axle and rotating handle in the place of the old pump-arm or lever.

The same letters always indicate `the same parts in all the drawings.

Figure l is a sectional view of the whole pump.

Figure 2 is a' plan view of the top ofthe valve, which is claimed as an improvement.

Figure 3 is a view of the bottom of the valve.

In the drawingsa is a stanchion, or support forthe axleb, to which are fastened, ou the one end, the crank c, and on the other side vthe disk d, which is att-ached, by means of the connecting-rod c, tothe pipe and pump at f. One of the features ofthe improvement herein 'claimed is the substitution-of this crank, axle, disk, and connectingrod for raising and lowering the pump, in the place of the old-fashioned arm, or lever. The other feature'of improvement clahned is the peculiarly-constructed valve, represented by the colored sections in Iig-.1, and by figs. 2 and 3.

' A is the piston-rod, (of metal, of course,) with iiange all around it, extending to the inner circumference of the pump, with holes at :v for the water to gnsh through when the valve or piston is descending.

B, in red lines, is the core, fitting upon A,.and faste ened to it by the caps, with the screw c' in its centre. C, in blue lines, is an outside rim, made in sections.

In this'case,vthere are four of these sections, the partn is a wire, .made of brass` or steel, which serves as a spring to keep the piston expanded. Itis kept in place by. beingrun through holes in thin webs y.

The yellow sectioning in iig. 1, represents a leather ring, running quite around the inner circumference of, the pump, fastened to the bottom of all four sections ofthe rim (l by rivets, and it serves both as a stopper over the holes x and to keep the piston tight in the pump.

I claim, as my invention- The pump-valve, composed of the rod A', with the flange perforated at x; the core B, with the openings m and the lugs o; the rim (l, in sections, with the notches for lugs o and the thin webs y the cap s and screw i; the leather ring r, and the wire spring n, all arranged and constructed as described, for the purpose described.

Dated the 31st day of December, 1868.
